Acute myeloid leukemia (AML) carrying NPM1 mutations and cytoplasmic nucleophosmin (NPMc+ AML) accounts for about one-third of adult AML and shows distinct features, including a unique gene expression profile. MicroRNAs (miRNAs) are small noncoding RNAs of 19-25 nucleotides in length that have been linked to the development of cancer. Here, we investigated the role of miRNAs in the biology of N...
Nucleophosmin (NPM1) is an abundant, nucleolar tumor antigen with important roles in cell proliferation and putative contributions to oncogenesis. Wild-type NPM1 forms pentameric oligomers through interactions at the amino-terminal core domain. A truncated form of NPM1 found in some hepatocellular carcinoma tissue formed an unusually stable oligomer and showed increased susceptibility to cleava...
G, Wassmann B, et al. Sustained complete molecular remissions after treatment with imatinib-mesylate in patients with failure after allogeneic stem cell transplantation for chronic myelogenous leukemia: results of a prospective phase II open-label multicenter study. J Clin Oncol 2005;23:7583-93. 8. Dazzi F, Szydlo RM, Craddock C, Cross NC, Kaeda J, Chase A, et al. Comparison of single-dose and ...
Monitoring minimal residual disease is an important way to identify patients with acute myeloid leukemia at high risk of relapse. In this study we investigated the prognostic potential of minimal residual disease monitoring by quantitative real-time polymerase chain reaction analysis of NPM1 mutations in patients treated in the AMLCG 1999, 2004 and 2008 trials. Minimal residual disease was moni...
Nucleophosmin/B23 was first identified as a nucleolar protein expressed at higher levels in cancer cells compared to normal cells. Nucleophosmin/B23 has long been thus thought to have a role in tumor formation. With our efforts and others in the last 15 years, nucleophosmin/B23 has proven to have an oncogenic role. In this review, we provide evidence suggesting that nucleophosmin/B23 may be a c...
Acute myeloid leukemia carrying cytoplasmic mutated nucleophosmin (NPMc(+) AML) and blastic plasmacytoid dendritic cell neoplasm have been included as new entities in the 4(th) edition (2008) WHO classification of myeloid neoplasms. These conditions may show clinical and pathological overlapping features (leukemic and skin involvement, and expression of macrophage markers). In this study, we pr...
Aim: Lung cancer is the leading cause of mortality from across world. In this study, use serum nucleolin (NCL) and nucleophosmin (NPM1) levels as a marker in diagnosis, prognosis treatment response evaluation lung was investigated. Materials Method: NCL NPM1 samples taken before chemotherapy after 3-4 courses control group patients diagnosed with were studied using ELISA method. Results: Serum ...
Mutations in the nucleophosmin (NPM1) and fms-like tyrosine kinase-3 (FLT3) genes are the most commonly observed mutations in patients with normal-karyotype acute myeloid leukemia (AML-NK). We analyzed the prognostic effects and interactions of these mutations in 201 AML-NK patients. NPM1 and FLT3 mutations were found in 38.3 and 24.9% of AML-NK patients, respectively. NPM1 mutations (NPM1mut),...
Mutations in the C-terminal region of nucleophosmin in acute myeloid leukemia (AML) result in aberrant cytoplasmic nucleophosmin (cNPM) in leukemic blast cells which is detectable by immunocytochemistry in bone marrow trephine (BMT) biopsy sections. We tested whether cNPM is detectable by immunocytochemistry in air-dried smears of AML with nucleophosmin1 (NPM1) mutations. An immunoalkaline phos...
This study was designed to perform an acceptable prognostic nomogram for acute myeloid leukemia. The clinical data from 311 patients from our institution and 165 patients generated with Cancer Genome Atlas Research Network were reviewed. A prognostic nomogram was designed according to the Cox's proportional hazard model to predict overall survival (OS). To compare the capacity of the nomogram w...
